MetalTech-USA is the authorized zinc sheet metal supplier through elZinc America in all of the USA for the commercialization of architectural zinc, elZinc. Whether natural or pre-weathered, zinc is a highly valued material for applications such as zinc roof construction and zinc wall cladding. It allows for great freedom in terms of aesthetics and architecture. It is a perfectly suitable building material for all types of construction both in classical and modern architecture.
MetalTech-USA and elZinc America rely on the precision in the composition of the alloy used to make zinc metal panels and the implementation of controlled lamination, which defines the thermo-mechanical processes and the material’s microstructural changes, as keys to both the processes and the product’s excellence.
- High malleability, regardless of the direction of rolling
- High stability once conformed
- Optimal electro-welding performance due to its low surface oil content
- Limited fragility at low temperatures.
- elZinc Natural
A metallic grey color zinc is exposed to weathering; the naturally formed patina layer protects it and provides it with exceptional resistance against corrosion and gives it its final grey color.
- elZinc Slate®
A matt grey pre-weathered zinc. It is used in zinc roof construction and on façades, or for interior work where the patina takes longer to form. It can be used in restoration and renovation since its initial color allows it to blend in easily with zinc already in place. The pre-weathering is performed using a non-polluting phosphate treatment that gives it a uniform appearance that would have been achieved after several years of exposure to the open air while preserving its initial properties.
- elZinc Rainbow®
A rolled zinc-titanium, manufactured from elZinc Slate® (with the exception of elZinc Rainbow gold) by applying mineral pigments. The 35 organic coatings provide additional anti-corrosion protection. Its natural, warm tones give it aesthetic value for both interior and exterior applications. After exposure to weathering, the naturally formed patina layer protects it and provides it with exceptional resistance against corrosion while giving it its final grey color.
